Claire DeWitt and the Bohemian Highway

Gran succumbs to sophomore slump in her second Claire DeWitt mystery (after 2011’s Claire DeWitt and the City of the Dead). An atypical PI who would be at home in a Hunter Thompson story, the sarcastic Claire relies on her dreams, mind-enhancing drugs, a computer-hacker assistant, and her professional bible, Détection by French detective Jacques Silette, to solve crimes. Claire has moved to San Francisco, where she’s caught up in the murder of her old boyfriend, Paul Casablancas, in what appears to be a botched robbery. She follows clues about Paul’s murder and comforts his rock-musician widow, Lydia Nunez, while investigating miniature horse thefts and while looking into the disappearance of an old friend who vanished during the 1980s in Manhattan’s East Village. Rehashed plot points, wearisome characters (Claire’s manic personality can grate), and a rushed denouement make this a lesser effort from a talented author. Agent: Barney Karpfinger, the Karpfinger Agency. (June)
